9 b125Fixed

Let's consider code below:

import javax.xml.bind.*;
import java.util.Map;

public class Test7 {
    private static JAXBContext tmp;

    public static abstract class FactoryBase implements JAXBContextFactory {
        @Override
        public JAXBContext createContext(Class<?>[] classesToBeBound, Map<String, ?> properties) throws JAXBException {
            return tmp;
        }

        @Override
        public JAXBContext createContext(String contextPath, ClassLoader classLoader, Map<String, ?> properties)
                throws JAXBException {
            return tmp;
        }
    }

    public static class Factory extends FactoryBase {}

    public static void main(String[] args) throws JAXBException {
        tmp = JAXBContext.newInstance(Test7.class);
        System.setProperty(JAXBContext.JAXB_CONTEXT_FACTORY, "Test7$Factory");
        JAXBContext.newInstance(Test7.class);
    }
}

It causes following output on JDK9b104 however it should have succeeded:

Exception in thread "main" javax.xml.bind.JAXBException: Provider class Test7$FactoryBase could not be instantiated: java.security.PrivilegedActionException: java.lang.InstantiationException

Thanks Mandy - yes that's what the patch I proposed on core-libs-dev does: http://cr.openjdk.java.net/~dfuchs/webrev_8150173/webrev.00/

The spec of JAXBContext states: The class is implementation of JAXBContextFactory. It must also implement no-arg constructor. If discovered in other step then 3, new instance using no-arg constructor is created first. After that, appropriate instance method is invoked on this instance. The bug may be just this line: Class<?> declaringClass = m.getDeclaringClass();

Daniel, the failing tests (in the binaries) are at: http://jre.us.oracle.com/java/re/jck/9/promoted/latest/binaries/JCK-runtime-9/tests/api/javax_xml/bind/JAXBContext/NewInstance_Classes/ http://jre.us.oracle.com/java/re/jck/9/promoted/latest/binaries/JCK-runtime-9/tests/api/javax_xml/bind/JAXBContext/NewInstance_ClassesMap/ http://jre.us.oracle.com/java/re/jck/9/promoted/latest/binaries/JCK-runtime-9/tests/api/javax_xml/bind/JAXBContext/NewInstance_StringClassLoader/ http://jre.us.oracle.com/java/re/jck/9/promoted/latest/binaries/JCK-runtime-9/tests/api/javax_xml/bind/JAXBContext/NewInstance_String/ http://jre.us.oracle.com/java/re/jck/9/promoted/latest/binaries/JCK-runtime-9/tests/api/javax_xml/bind/JAXBContext/NewInstance_StringClassLoaderMap/ They should be at a similar location in the latest bundles. I should also add that latest = b38 at the time I added this comment.
